Description
Part of the degradation domain taken from the HIF-1a protein in humans. Under normal oxygen conditions, prolyl hydroxylases target this domain for hydroxylation. The hydroxylated subunit makes the resultant protein a target for E3 ubiquin ligase when bound by the VHL gene product, leading to its proteasomal degradation. When fused to the luciferase, and following a strong, mammalian constitutive promoter, it should indicate low levels of oxygen in cell populations.
Notes
The part has to mimic the activity of HIF-1a in mammalian systems by degrading at normal oxygen concentrations and upregulating at high oxygen concentrations. The fusion of the degradation domain to a reporter theoretically enables this activity.
Source
It comes from the HIF1A gene in homo sapiens sapiens.
